In the evening, mix together the sourdough starter, honey, and water. With a fork, mix until well combined.
Add the flour and salt to the mixture. Mix well. The dough will look shaggy and sticky. Cover with a damp dish cloth and let it sit in a warm, draft free place for 12-18 hours or until the dough has doubled in size. The dough should look very bubbly.
After the dough has fully risen, coat a pan with the olive oil. Remove the dough from the bowl and place it in the pan. Turn the dough over in the pan so it is coated in olive oil on both sides. Cover with a damp cloth and let it rise for another 2 hours.
After 2 hours, preheat the oven to 425 degrees.
With wet fingers, dimple the dough and gently stretch the dough. If it doesn't reach the edges of the pan, that's ok. Add toppings at this time, or just coarse salt.
Bake for 30-35 minutes or until the focaccia is golden brown and the edges are crispy.
